Definitions

  • This invention relates to a method and apparatus for forming wire reinforced sheets of elastomeric material such as a tire reinforcing belt or ply material.
  • calendering can process more material faster, is capable of processing materials that are tougher or less homogeneously mixed at lower temperatures than an extruder.
  • the extruder requires very uniformly mixed or homogeneous materials. This means that the elastomeric material must make at least three, usually four, passes through a mixing apparatus, commonly known in the art as a Banbury mixer.
  • the material can be fed into an extruder.
  • the extruder forces the material through a die thereby encapsulating the wires.
  • the least bit of debris or dirt can block a portion of the die orifice resulting in the production of scrap, excessive maintenance time and inherently higher costs.
  • the present invention employs the best attributes of both calendering and extruding while simultaneously minimizing the worst or less desirable characteristics of each process.
  • a method for fabricating a rubberised wire sheet comprises the steps of passing a plurality of wires through an extruder to coat each of the plurality of wires with rubber to form a plurality of rubberized wires, and then passing the plurality of rubberized wires through a calender roller system to form a rubberized wire sheet having a desired width.
  • the method further may comprise the step of coating the plurality of rubberized wires with rubber while being passed through the calender.
  • the above method permits the wires to be rubberized with a first compound and then encapsulated in a sheet of rubber of a second rubber compound having differing properties from the first compound.
  • the above method may be carried out by utilizing an apparatus for fabricating the rubberized wire sheet.
  • the apparatus comprises an extruder and a calender.
  • the extruder coats a plurality of wires passing through the extruder with rubber to form a plurality of rubberized wires.
  • the calender further coats the plurality of rubberized wires passing through the calender to form a rubberized sheet having a flat surface, the rubberized wires being fed from the extruder to the calender roller system.

  • Fig. 13 is a partial perspective cross-sectional view of a tire employing a rubberised wire sheet according to the present invention.
  • Figs. 4 and 4A illustrate a prior art method of forming a rubberized wire sheet or ribbon of material.
  • the teachings of this prior art method are disclosed in U.S. Patent Nos. 3,803,965, 3,888,713 and 4,274,821 and are incorporated herein by reference.
  • the above-referenced patents are commonly owned by The Steelastic Company of Akron, Ohio.
  • the standard prior art Steelastic method of extruding rubberized sheets starts with the supplying of wires 100. All wire stock is stored and let off from within a temperature and humidity-controlled creel room.
  • the wire 100 is supplied as individual cords wound onto 80-lb spools.
  • the spools are mounted on creel stands, each spool being placed on an individual horizontal pin. Some stands just have fixed pins, some have an air-controlled letoff brake to control wire tension.
  • the wire cords pass over a series of rollers and through a set of ceramic eyelets.
  • the wires 100 are all grouped together into a narrow sheet of wires, just before they pass through a window out of the creel room. They remain in this horizontal sheet right into the extrusion section of the process.
  • the sheet of wires 100 enters a machined extrusion head 120.
  • This head is split into two parts along a horizontal plane.
  • a cold feed extruder 10 is attached to the head 120 at a right angle to the wire path.
  • the head 120 is designed to turn the rubber flow and to cause it to flow around and in between the wires 100, completely coating the wire sheet.
  • the head 12o also holds the wire die 140 and insert 160 in place. The insert is drilled to the desired wire spacing for a given wire code. All the wires 100 are individually threaded through this insert.
  • the die 140 holds the insert 160, and both are held in place by the head 120.
  • the rubber 101 flows around the wire 100 as it passes through the head, forming the extruded sheet 102.
  • the die 140 also may preferably form a small "lip" 104 along one edge of the sheet. This lip 104 is necessary for lap-splicing the extruded sheet 102 later in the process. Alternatively, the die 140 may simply form the sheet 102 with no "lip" in which case the sheet 102 may be butt spliced in a later process.
  • the extruder speed is controlled by a pressure control system.
  • the pressure of the rubber in the head is read by a transducer.
  • the control system regulates the extruder screw speed to maintain the desired head pressure.
  • the head 120, the extruder screw, and the extruder barrel are all temperature-controlled by external temperature control units.
  • the extruded sheet After exiting the extruder 10, the extruded sheet enters the pull roll/cooling can assembly. This consists of a series of five rolls over which the sheet is fed. The last two rolls are driven by a constant-speed AC motor, which is coupled to the rolls through an electromagnetic clutch. These rolls pull the extruded sheet 102 away from the extruder section 10, and supply it to the cutting/splicing section. The speed of the roll is read by a tachometer, and the current to the clutch is varied by the control to maintain the desired setpoint speed.
  • the cutter/splicer includes a pickup ram, a cutting knife, and an indexing conveyor.
  • the ram is a long narrow assembly, slightly narrower than the strip width, which is powered by a DC drive.
  • the bottom surface of the ram is drilled with small holes leading to the hollow core of the ram.
  • a flexible hose connects the ram to an air/vacuum manifold.
  • the ram is moved forward and back (along the direction of strip extrusion) by an indexing DC drive. It is also raised and lowered by a rack-and-pinion/air cylinder assembly.
  • the knife is a guillotine knife assembly.
  • the cutting is done by a pair of knife blades - a stationary lower blade, and an upper blade, which is raised and lowered by an air cylinder.
  • the upper blade unit pivots at one end, and is backed by a set of springs at the other end. The blades cut in a scissors action.
  • the indexing conveyor is a horizontal table equipped with a 36" or less than 1 meter wide conveyor belt.
  • the belt is advanced by an indexing DC drive.
  • the entire conveyor assembly can be rotated in the horizontal plane. This allows any desired belt cord angle to be produced.
  • the ram starts in the up position, advances over the end of the extruded sheet in the lead-in chute, lowers onto the extruded sheet, vacuum is applied to the ram (causing the extruded sheet to stick to it), the ram is raised and retracted (pulling the sheet forward through the gap between the knife blades), the ram is lowered to the indexing conveyor, the upper knife blade drops (cutting the sheet), air is applied to the ram (causing the sheet to be released), the ram raises, and the conveyor indexes forward.
  • the conveyor indexing distance is adjusted so that when the ram brings the next section of sheet down to the conveyor, the leading edge of the sheet is pushed onto the "lip" of the previous piece, causing a lap splice to be formed. As this process repeats, a belt of the desired final width and belt angle is produced.
  • the improved method and apparatus for forming a rubberized sheet 202 is illustrated.
  • the apparatus includes much of the above described equipment and a calender 50 and a modified extruder die 206.
  • the wires 200 are fed from the creel room through an aligning fixture 204 and then into the modified extruder die 206.
  • the modified die is designed with an opening 207 for each wire 200.
  • the rubberized wires 201 are then fed through an organizer or aligning rollers 205 prior to entering the calender 50.
  • the calender 50 is a small "inverted L" 4-roll calender. It includes 4 flat-face rolls 51,52,53,54 which are geared together and driven from a single DC drive system. The rolls 51,52,53,54 are cored and supplied with water for cooling and heating. The gap 55 between the rolls can be adjusted to alter the rubber gage thickness T.
  • Banks 61,62 of rubber are maintained between the bottom pair of rolls 51,52, and between the top pair of rolls 53,54.
  • the rolls 51,52 form a bottom sheet 214 and the rolls 53,54 form a top sheet 212 of rubber, respectively.
  • the bottom sheet of rubber 214 is separated with a brass "plow” knife 70 on the entrance side of the calender 50. This is needed for forming the "lip" 208 on the calendered sheet 202.
  • the rubberized wires 201 pass under and around organizer rolls 205, and turn from the horizontal plane and angles up to an idler roll 209 on the entrance side of the calender 50.
  • the rubberized wires 201 turn around the idler 209, and pass under and around another organizer roll 205, and then pass between the center two rolls 52,54 of the calender 50.
  • the upper and lower sheets 212,214 of rubber are laminated onto the rubberized wires 201.
  • the sheet material 202 passes through to the other side of the calender.
  • the sheet 202 is cut to width with a pair of cutting blades 77.
  • the sheet 202 exits the calender 50, passes overhead on a series of idler rolls, and then enters the cooling can/pull roll assembly.
  • the scrap material 216 stays on the calender roll and returns to the top bank 61 of rubber.
  • An important feature of the above-described method and apparatus is the ability to coat the wires 200 with a first compound 210 of rubber and then encapsulating the rubberized wires in a sheet of rubber of a second or differing rubber compound 218.
  • Fig. 5 illustrates a portion of a rubberized sheet 220 made according to one embodiment of the invention.
  • the sheet 220 illustrates the calendered second compound 222 encapsulating a sheet 225 of rubberized wires 224 of the first compound 226.
  • the rubberized wire sheet has edges adapted for butt splicing.
  • Fig. 6 is similar to that illustrated in Fig. 5; however, the sheet 230 has rubberized wires 234 which are individually coated with the first compound 236 and not joined into a web or sheet of first compound material 236.
  • the embodiment illustrated in Fig. 6 is preferred because it minimizes the amount of first compound rubber 236 required.
  • the first compound rubber 236 being processed through the extruder is believed to be more costly due to the required homogeneity needed to feed through the extruder die.
  • the first compound 236 is of a lower viscosity than the second compound 235 generally.
  • the second encapsulating compound 235 being formed by calendering is believed to be more economical.
  • UH12 wire 200 was shown, the wire 200 being stranded 12x.20+1HT Open, 12EIP the overall wire diameter equaled .043 inches (1.1 mm) excluding the wrap wire, the wrap wire having a diameter of 0.006" (0.15 mm).
  • the above apparatus and method permits the wires 200 to be coated with rubber having a high sulfur content.
  • sulfur content above 2 parts per hundred rubber (phr) is considered high sulfur content for good wire adhesion 3 to 10 phr, preferably 5 phr is used.
  • sulfur improves wire adhesion, high sulfur reduces aging resistance, resilience, interfacial adhesion and other physical properties.
  • High sulfur content rubber compounds exhibit excellent adhesion to wire; however, the sulfur migrates in a process called blooming. The migrating sulfur forms a chalking residue at the surface of the belt or ply. This residue adversely affects the adhesion characteristic of the belt to the adjacent uncured components such as the tread. Heretofore, the use of such compounds was very difficult.
  • the present invention permits high sulfur content rubber to be coated onto the wire 200.
  • the rubberized wire 201 is then encapsulated in a conventional lower sulfur content rubber compound 218.
  • the resultant "blooming" effect is prevented because the sulfur in the high sulfur rubber cannot migrate to the oxidizing exterior surfaces prior to curing the rubber in a process called vulcanization.
  • the amount of first compound rubber 236 employed as illustrated in Fig. 6 can be varied from 5% to 90% of the total rubber content, preferably the first compound is less than 20 percent of the total rubber content while the calendered second compound 235 represents the remaining 80 percent or more.
  • the calendered second compound 235 requiring less processing and handling can presumably be more economical.
  • the calender 50 providing the majority of the material permits the extruded material to be minimized. This in turn means that the extruder and calender can operate at or close to their maximum speeds.
  • the calender being the faster component means that the overall apparatus can approach the speed capable of a calender.
  • the linear throughput of sheet material can be expected to increase when compared to the prior art Steelastic extruder system 10.
  • Figure 7 illustrates the alternative method which permits the wires 200 to pass through the organizer roller with the extruder die head 80 opened or removed.
  • the uncoated wires 200 are then fed into the calender 50 and encapsulated between the two sheets 212,214 of calendered rubber, thus forming a rubberized wire sheet 203.
  • the machine speed is limited by the calender speed which is believed to be the most efficient.
  • the prior art Steelastic pull roll/cooling can assembly was slightly modified.
  • the electromagnetic clutch on the pull roll was switched to constant torque control rather than the prior art constant speed. This modification is needed because the calender 50 must establish the line speed.
  • the pull rolls slip from the drive motor when a preset torque is reached. This causes the pull roll assembly to act as a "follower” to the calender 50. This also maintains a relatively constant tension in the calendered sheet between the calender 50 and the pull roll.
  • the standard Steelastic pull roll control system was modified by adding another circuit board to the Eaton Dynamatic AC electromagnetic clutch/drive system. This is a standard option available from Eaton Corporation.
  • the apparatus is capable of forming a gum lip 208 of material along one edge of the sheet 202,203.
  • the method of manufacturing a fabric or cord-reinforced laminate material, the fabric or cord 200 having a predetermined width W comprises the steps of:
  • a small brass wedge shaped "plow” knife 70 rides against the face of one of the lower rollers 52.
  • the face 72 of the plow knife 70 is a narrow triangle, with one long side 73 of the triangular face 72 parallel to the direction of rubber stock travel on the roll 52. This side and the apex 74 of the triangular face 72 cut an edge 221 on the incoming lower rubber sheet 214. The other long side 75 of the triangular face 72 directs the scrap portion 216 of the lower rubber sheet 214 away to the side.
  • a clean edge 221 has been formed on the process rubber sheet 214, and the process rubber sheet 214 and the scrap rubber sheet 216 have been separated by the width of the base side 76 of the plow knife triangular face 72.
  • the process and scrap portions 216 of the lower rubber sheet 214 then pass through the nip 58 of the calender 50.
  • the process portion of the lower rubber sheet 214 and the upper rubber sheet 212 are calendered onto the wire 200.
  • the calendered material is then cut on both sides with standard fixed knives 77, which brings the calendered material to its final width W1+W2.
  • the slight difference in lateral position between the cutting edge of the plow knife 70 and the right fixed knife 77 creates the gum lip or stepped edge 208 that is needed for lap splicing the stock in the next process.
  • the calendered material then leaves the face of the calender roll 50 and travels over several idler rolls into the next process.
  • the scrap material 216 (consisting of two layers of rubber, laminated together at both edges of the roll), continues to adhere to the roll, and then enters the rubber bank 61 at the top nip 57 of the calender 50.
  • the plow knife 70 is held to the side frame of the calender 50, using two tool slide mechanisms 66,67. These allow the position of the plow knife 72 to be adjusted, both in and out of the roll 52, and along the face of the roll. This permits precise adjustment of the "stepped edge" side 208 of the calendered material.
  • a standard knife such as 77 could cut one edge 221 of the first layer 214 of rubber, it was determined that the scrap material 216 could not be allowed to pass through the nip. Since the scrap material 216 and the process sheet material 214 were only separated by the thin knife-cut, the scrap 216 and process sheet material 214 would stitch back together as they passed through the nip.
  • the plow knife assembly 65 simplifies the operation by eliminating the need for the idler roll, the cutting of the leading edge of scrap, and the need for an operator to be there to pull away the scrap strip.
  • the plow knife 72 is simply advanced into contact with the calender roll 52 by means of a hand-cranked tool slide 66. Side-to-side adjustment is achieved by means of the hand crank slide mechanism 67.
  • the scrap material passes through the nip 58 of the calender 50, and continues with all other scrap material 216 in to the bank 61 at the top nip 57 of the calender 50.
  • Another advantage of this design is that almost all scrap strip 216, which would normally accumulate on the floor and then be discarded, is now returned to the top bank 61, where it is recycled into the process rubber. With use of this design, there is very little scrap associated with the calender process.
  • This design is also inherently safer than the use of a standard knife since the operator is not required to place his hands near the cutting knife or the nip of the calender.
  • a plurality of rubberized sheets 202 are shown assembled at lap splices.
  • the plurality of assembled sheets form a rubberized wire reinforcing member such as a belt or a ply, such belts or plies being commonly used in the manufacture of pneumatic tires.
  • Fig. 11 illustrates the preferred wire spacing within each sheet 202.
  • the wires are uniformly spaced a distance d, the distance and each edge is set at about 1/2 d.
  • the distance d is slightly inclined such that when the ply is stretched, a spacing of "d" is achieved at the splice.
  • the rubberized wire sheet 202 can be employed in a tire 20 as illustrated in Fig. 13.
  • the tire 20 has a ground engaging tread 12, a carcass 14 having a pair of annular beads 24, a pair of sidewall members 21 extending radially outward from the beads 24, and a pair of reinforcing plies 18 wrapped about the annular beads.
  • the tire has at least one reinforcement member 202 having a plurality of axially spaced wires 201, each wire 201 being individually coated with a first elastomeric compound 210, each individually coated wire 201 being encapsulated in a layer of a second elastomeric compound.
  • the reinforcing members 202 are commonly referred to as belts.
  • the tire 20 as illustrated includes an innerliner 17, an apex 16 located radially outward of the bead 24, a chipper 25, and an elastomeric chaffer 23.
  • the chipper 25 may include rubberized wires 201, the wires 201 being coated with the first compound 210 and encapsulated within a second compound 218. Additionally, the plies 18 may have the coated wires 201 as reinforcing cords encapsulated as described above. In the preferred embodiment, it is desirable to employ a first compound having a high sulfur content as previously described while the second compound employs a more conventional level or even a reduced level of sulfur.
  • the tire 20 preferably has each wire of the reinforcement member coated with the first compound such that the wire having a diameter measured in the cross-section of the wire is coated by the first compound, the first compound having a diameter measured in the cross-section in the range of 150% to 400% of that of the wire. It is believed desirable that the first compound have a cross-sectional diameter of at least 200% of the wire diameter.
